VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 25, 2009) -

NOT FOR DISSEMINATION IN THE UNITED STATES OF AMERICA

Rhino Resources Inc. (TSX VENTURE:RHI.P) (the "Company" or "Rhino"), a Capital Pool Company ("CPC"), and ImmunoVaccine Technologies Inc. ("IVT") are pleased to announce that their respective shareholders have approved the Arrangement Agreement (the "Agreement") reflecting the terms of a binding term sheet dated effective June 1, 2009 for Rhino's acquisition (the "Transaction") of IVT. The details of the Transaction were included in press releases dated June 8 and August 19, 2009 and certain information is updated or reported herein. The Transaction has been approved as Rhino's qualifying transaction by the TSX-Venture Exchange (the "Exchange"), subject to certain conditions. IVT is a private company, based in Halifax, Nova Scotia, incorporated under the Companies Act of Nova Scotia (the "Act") on March 28, 2000.

The Concurrent Financing, described herein, is expected to close on September 29, 2009, subject to the issuance of the final Exchange Bulletin. As of this date, the Concurrent Financing is expected to result in gross proceeds of approximately $8.3 million through the issuance of approximately 11.9 million common shares at $0.70 per share.

Trading Halt Request

Rhino's shareholders have also approved the consolidation of the Company's shares on the basis of one new Rhino common share ("New Common Share") for each five existing Rhino common shares (the "Rhino Share Consolidation"). The Company has requested that the Exchange halt trading of the common shares of Rhino from September 28, 2009 until the Exchange has issued its final Exchange Bulletin. As part of the Transaction, the Company will change its name to ImmunoVaccine Inc. and will commence trading under the symbol IMV.

The Transaction

The Agreement provides that, subject to the fulfillment of certain conditions, the Transaction will take the form of a share exchange whereby Rhino will acquire all of the issued and outstanding common shares of IVT in consideration for common shares of Rhino. In order to effect the Transaction, Rhino and IVT have entered into a plan of arrangement (the "Plan of Arrangement") and will seek court approval thereof in accordance with the provisions of Section 130 of the Act.

Pursuant to the Transaction, Rhino shares will be consolidated on the basis of one New Common Share for each five existing Rhino common shares and each one existing IVT common share will be exchanged for one New Common Share (the "IVT Acquisition"). There are currently 12,000,000 Rhino common shares issued and outstanding which will be consolidated into 2,400,000 New Common Shares and 30,601,110 IVT common shares issued and outstanding which will be exchanged for 30,601,110 New Common Shares in the capital of Rhino. Rhino's New Common Shares will be issued at a deemed Issue Price of $0.70 per share ($0.14 per share pre-consolidation) and the total consideration payable to IVT shareholders is deemed to be valued at $21,420,777.

Upon closing of the Transaction, 2,790,437 outstanding IVT options entitling the holders to purchase a total of 2,790,437 common shares of IVT at an average price of $0.59 per share will be converted into an equal number of Rhino options with no adjustment to the exercise price. Also upon closing of the Transaction, 93,143 IVT warrants entitling the holders to purchase 139,714 common shares of IVT at an average price of $1.17 per share (each warrant exercisable into 1.5 common shares at an exercise price of $1.75 per warrant) will be converted into 139,714 Rhino warrants exercisable into 139,714 common shares at an exercise price of $1.17 per share.

Rhino's shareholders have also elected Wade K. Dawe, Denis Ryan, Randal Chase, Michael Kirby and William Cochrane, being five of the existing six directors of IVT, as directors of the Company to hold office until the next annual meeting of the Company. Brian MacEachen, Terry Christopher and Keith Abriel, currently serving as directors of the Company, will resign following approval of the Transaction by the Exchange.

IVT has recently hired Mr. Gary Dodge as Chief Financial Officer. Mr. Dodge is a Chartered Accountant with extensive experience in financial reporting and capital markets. Mr. Dodge joins IVT from SolutionInc Technologies Limited where he has served as Chief Financial Officer since 2007. In joining IVT's executive, Mr. Dodge has been granted 75,000 stock options at a strike price of $0.70 per option and an expiration date of September 4, 2019. Mr. Dodge will serve as Chief Financial Officer of the resulting issuer.

Assets of the Resulting Issuer

IVT, with facilities in Halifax, Nova Scotia, is a clinical-stage biotechnology firm which has patented vaccine delivery and enhancement technologies trade named VacciMax® and DepoVax™ with a strong early stage pipeline of infectious disease and cancer vaccine products.

IVT owns an intellectual property portfolio for its VacciMax® platform technology, including 18 granted patents and applications in Canada, US, Europe, Australia and Japan. US Patent 6,793,923 (issued in 2004) contains very broad claims to IVT's platform, covering "any antigen, any adjuvant in any liposome and any oil". The platform name is protected by trademark in the US and Europe. IVT has also filed additional patent applications to protect DepoVax™ formulations as well as delivery of oligonucleotides and others.

IVT's vaccine delivery and enhancement technology has achieved 100% tumor elimination in three independent pre-clinical models as well as reducing the number of doses required for efficacy of infectious disease vaccines from two or three to a single dose. IVT has developed a therapeutic vaccine against ovarian, breast and prostate cancer that, in conjunction with its vaccine delivery technology, is being readied to enter Phase I human clinical trials. IVT will pursue a fast-track regulatory strategy by taking the product through a short Phase I into a Phase II clinical trial. In addition, IVT is conducting pre-clinical studies for two infectious disease vaccines: single dose pandemic influenza and Hepatitis B.

While IVT's technology is early stage, it has characteristics of a later stage entity. Use of IVT's delivery technology for human health applications has been evaluated in not just one, but a wide variety of preclinical therapeutic cancer and prophylactic infectious disease animal models. IVT has endeavoured to license the delivery technology to large health companies for use and has already licensed some uses to Pfizer Animal Health for livestock vaccines, generating its first revenues in Q1 2008.

IVT is committed to advancing an infectious disease and a therapeutic cancer vaccine into a Phase I clinical trial and plans to follow with Phase II trials, where justified with Phase I data to maximize value. At this date, IVT plans to do this sequentially, and will take only one product into a Phase I clinical trial in order to demonstrate safety and early efficacy of the DepoVax™ platform. The other products will follow at the appropriate time.

IVT has completed crucial scale-up and manufacturing method development for the DepoVax™ platform which is applicable to all of IVT's subsequent human health vaccines. The scale-up methods have been transferred to a reputable contract GMP(1) development and manufacturing facility. This site has an establishment license from Health Canada, which allows it to manufacture sterile products for clinical and commercial purposes. Dedicated, IVT-owned equipment has been purchased and installed at the site.

IVT has manufactured commercial scale vaccine batches, including the most recent 50 litres (200,000 doses) of a Hepatitis B vaccine. This accomplishment is particularly important because historically, large-scale production of liposomes has been a significant challenge. IVT has confirmed both the stability and that the biological activity of the batch is equivalent to IVT's laboratory batches.

Concurrent Financings

As a condition to closing the Transaction, and subject to any necessary approvals, IVT will complete equity financings (the "Concurrent Financings") following and conditional on the Rhino Share Consolidation. As of the date of this release, it is expected that approximately 6.2 million IVT shares will be issued pursuant to a brokered private placement and 5.9 million IVT shares will be issued through subscription by existing IVT shareholders resulting in the issuance of approximately 11.9 million IVT common shares priced at $0.70 per share for gross proceeds of $8.3 million. Blackmont Capital Inc. is the lead agent of the brokered private placement and SP Angel Corporate Finance LLP and Beacon Securities Limited are Co-agents. The agents will earn an aggregate 8% cash commission on the brokered private placement and will receive agents' warrants entitling the agents to acquire IVT common shares, equal to 8% of the shares issued pursuant to the brokered private placement, at a price per share of $0.70 and expiring 12 months following the closing of the Transaction.

Rhino and IVT intend to use the proceeds of the financings to enter Phase I human clinical trials for IVT's therapeutic vaccine against ovarian, breast and prostate cancer, in conjunction with its vaccine delivery technology. Rhino and IVT plan to pursue a fast-track regulatory strategy by taking the product through a short Phase I and, if successful, into a Phase II clinical trial.

Following completion of the Transaction, including the Rhino Share Consolidation, the IVT Acquisition, and the Concurrent Financings, there are expected to be 44.9 million common shares of Rhino outstanding (excluding the exercise of any options or warrants issued pursuant to the financing).
